SPECIFIGATION forming part of Letters Patent No. 625,567, dated May 23,18979. Application filed March 2. 1897. Serial No. 625;'735; (No model.)

To 'all whom t may concern.:

Be it known that I, Janus L. Knvofsromof Boston, in the county ofSuffolk and State of Massachusetts, ,have invented an Improvement inFasteners, of which the following description, in connection with theaccompanying drawings, is a specification, like letters on a verticalsectional view-of my invention as form of spring-clip shown in Fig. l.

it may be embodied in a rug-fastener shown in place. Fig. 2 is a planview of the fastener proper, Fig. 2 being a view in detail of the Fig. 3is a` plan view of the stud to which in Fig. l the fastener is shown asapplied. Fig. 4 illustrates a form of stud member adapted to be usedwhen two layers of fabric are to be united, it being attached to onelayer in position to cooperate with a housing member o'n the otherlayer, as shown in Fig. 1.

In Figs. l to 3, inclusive, I have shown the fastenerl as built up fromsheet material and consisting, primarily, of an upper member centrallyswaged or spun or otherwise raised above the plane d of attachment inwhich lies the dange or web-like portion of the blank of metal or othermaterial from which it is made to form the housing fl",into which thehead of the fastening-stud L may ent-er.

To engage the fastening-stud and hold the fastener firmly thereto, Ihave provided a clip made of a fiat spring F, (best seen in Figs. 2 and21",) split throughout the greater part of its length and having thesplit enlarged at about the middle to form an attaching-aperture f,adapted to receive the head of the stud, the legs of the spring f and f2coming into gripping engagement with the neck of the fasteningstud L,which preferably has, as illustrated, a groove l, into which the saidlegs enter, so that the head ZX of the stud pre*- vents accidentaldisplacement of the springclip therefrom. As one suitable and strongmeans for securing-this spring-clip to the upper member I have shown theflat portion or web d of the latter as recessed in the in,`

. stance illustrated by cutting material "away at d2 to form a seat forthe clip F, the headl nular plate h, extending entirely across the lowersurfaceofthe upper member d, to which it may be affixed by crimping theedge of one over that of the other, as illustrated, or in any othersuitable and desired manner. plate has a central aperture h opposite theaperture f of the clip and approximately of the same size as the latter,and it not only serves to hold the clip in place, but also to protectthe latter by insuring proper relative position of the fastener and studbefore the fastener can be forced down upon the stud.

It is often desirable to change the position of this class of device onthe fabric, &c.', to which it is secured, and While fasteners are inexistence which are merely sewed to the fabric and may therefore afterremoving the stitches be secured to another part of the fabric in asimilan manner, and While my present fastener offers no obstacle to theuse of suoli securing means, if itis desired to perforate its membersslightly, as indicated at d4, Fig. 2, I have shown securing means whichI believe to be novel and which afford means This j to readily and atany time enable removal by IOO a seater to receive and engage thethreaded post h2. In applying the fastener to the fabric P the post h2is forced up betweenthe fibers of the fabric at the desired spot untilthe end ap'- pears above the fabric,when the nut or equivalent device Kis screwed or fastened down upon-it, fthe material of the fabric-in theregion. of the device beingl clamped between the housing member and itssecuringmeans. Obviously upon unscrewing the nutthe operator canrelocate the fastener where desired.

Whilel haveillustratedthe housing d' as rounded,it is-within the scopeof 'my'invention to give it any convenient form, and instead ofproviding it with a post h2 it.may be furnished with a threaded apertureand the device K be provided with a threaded post tol enter the same.

It will be noted that the threaded opening in the nut, as shown in Fig.1 which receives the threaded post h2 extends but .partially through thenut, so as 'to'leave the top of the latter smooth and free fromdepressions that would tend.` to collect dirt and be a general nuisance.

As a convenient` form of stud member I have shown at L an annular memberadapted to receive in its central aperture a securingscrew or the likemeans, by which it inay. be fastened ,to the fio'or, dac., and having aneck contracted as described at l; but, however, my fastener may be usedwith any suitable form of fastening-stud.

Inasmuch as it is often equally desirable that not only the fastener,but the fasteningstud, may be adjustable upon the fabric, particularlyWhere rugs are used upon carpets, use may be made of any suitable studadapted to be attached removably to the fabric. One form of such aremovable stud I have illustrated in Fig. 4, where the upper memberm hasa grooved head m and a central threaded recess m2, and the lower platenhas a threaded post n to pass through the fabric 0 and enter intoengagement with the threaded recess m2, whereby the fastening-stud isattached to the fabric, the latter being clamped between the plates. l

I do not restrict my invention to the exact contour shown, since thesame may be varied considerably without departing froln the spirit of myinvention'.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. Acarpetorrugfasteningdevice, consisting of a stud member adapted tobe fastened to the floor or support, a housing provided with aspring-clip adapted to engage said stud member said housing beingprovided with a vertically-projecting post adapted to pass through thecarpet or rug to be fastened, and

a holding member detachably arranged upon `said post for detachablyholding the carpet or rug between it and said housing.

2. A carpet or rug fastening device, consisting of a stud member adaptedto be fastened vertically-projecting threaded .post `adapted to passthrough the carpet or rug to be fastened, and a nut partially threadedupon said threaded post for detachably holding the carpet or rug betweenit and said housing, the

. post receiving the 'threaded opening in said nut and extending butpartially throughthe latter so as to leave the top of the nut smooth andfree from depressions, for the purpose speciiied.

4. A carpet or rug fastener comprising a .spring-clip F of flat metalhaving a head f3,

and legs or grippingmembersf, j?, apertured-atj to receive a suitablefastening-stud' or the like; and housingorsupporting means for saidclip, said means comprisingY a lower plate apertured to permit entranceof said fastening-stud, and an upper housing member having a centralportion raised to clear said fastening-stud, and an integral hangedportion recessed to receive said clip; said plate and upper housingmember `being secured together with said clip embraced between them; andmeans by which said fasten-er may be attached to a carpet or rug.

5. A carpet or rug fastener comprising a spring-clip Fof fiat metalhaving a head fs and legs or gripping members f', f2, apertured at f toreceive a suitable fastening-stud por the like; and housing orsupporting means for said clip, said means comprising a lower plateapertured to permit entrance of said fastening-stud, and an upperhousing member having a central portion raised to clear saidfastening-stud, and an integral flanged portion recessed to receive saidclip; said plate and upper housing member being secured together withsaid clip embraced between them; and means by which said fastener may beattached to a carpet or rug; said means coniprisingavertically-projecting post on said housing member and adapted to passthrough the carpet or rug to be fastened, and

a holding memberarranged detachably upon y said post for holdingdetachably a carpet or rug between it and said housing.

In testimony whereof l have signed my name to this lspecification in thepresence of two subscribing witnesses.
